US presidential rivals Barack Obama and Mitt Romney have spent the day before the election visiting key swing states and making final pitches to voters. Mr Romney went to Florida, where polls suggest he has the edge, and then to Virginia, New Hampshire and Ohio. Mr Obama appeared in Iowa, Wisconsin and Ohio, joined at rallies by Bruce Springsteen and rapper Jay-Z. The election will be decided in just a handful of states, with Ohio in particular seen as crucial to victory. President Obama was ending his re-election campaign in Des Moines, Iowa - the city where his bid for the presidency began in early 2007.  [Link]
